Can potted osmanthus be transplanted to the open field in autumn?

Potted osmanthus can be transplanted to the open field in autumn, and it is better to transplant in early spring.

Osmanthus fragrans seedlings grow and adapt in the same year, which is beneficial to overwintering and survival. The planting distance of osmanthus fragrans is at least 2m, and the planting density will affect the tree type. Planting requires transplanting with soil balls, shallow planting in deep pits, full irrigation after planting, more organic fertilizer application, and 1 times liquid fertilizer after survival. Usually pay attention to timely prevention and control of pests and diseases to facilitate growth.

Maintenance management:

Osmanthus fragrans grows fastest in spring and autumn and needs more water and fertilizer. Water and fertilizer management should be strengthened in these two seasons. It is best to choose liquid fertilizer or water-soluble fertilizer made by irrigation, which is beneficial to absorption. It can also be applied with decomposed organic fertilizer in holes or used as base fertilizer when changing pots. Topdressing 1 available nitrogen fertilizer in late March, 1 available phosphorus fertilizer and potassium fertilizer in July, and 1 organic fertilizer in June. Irrigation and intertillage weeding should be done in time after each fertilization. Usually, big trees branch 1 time a year, and young trees branch 1-2 times a year. Fertilization can be applied 1 time every year before branching or flowering. It is not suitable to apply heavy fertilizer in the early stage of spring sowing, and pig manure, Niu Fei and bean cake are the best fertilizers. Intertillage in time from May to September to keep soil moisture.

2. Most osmanthus fragrans are washed and dried. Except for watering and moisturizing when transplanting, irrigation is generally not needed, so good soil drainage is needed. However, Sijigui likes to be wet, so watering requires a clear distinction between wet and dry, and water should not be accumulated. Especially when flowering, don't have too much water to avoid rotten roots or yellow leaves falling off. So as not to cause falling flowers and buds. If the temperature is low in winter, it is necessary to control watering and keep dry and wet alternately. The evaporation in summer is large, so it is required to water frequently except in rainy days to avoid death due to drought.

Osmanthus fragrans is resistant to pruning, and the more pruning, the better. It is required to achieve a mushroom-like tree shape, and it only needs to be pruned continuously. Branches that are too dense should be sparse, and branches that grow particularly tall should be cut short to reduce water transpiration consumption. Prune once after flowering in autumn, and cut off branches that are too dense and overgrown. So that each side branch is left with short branches. The second pruning is carried out before germination in early spring, and the dead, sick, weak and insect branches are cut, so that the new branches occupy the upper position. Wipe off excess sprouted branches according to the shape of the tree.

4. The main diseases that harm osmanthus fragrans in the north are brown spot, leaf blight and anthracnose, and the main pests are scale insects, red spiders and aphids. The control method can refer to the control of common diseases and pests of osmanthus fragrans.
